Answer:
Option E; THEY ARE EQUAL.
Explanation:
Pulmonary ventilation is commonly referred to as breathing. It is the process of air flowing into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation).
Pulmonary ventilation involves three different pressures: atmospheric pressure, intraalveolar (intrapulmonary) pressure, and intrapleural pressure.
Atmospheric pressure is the pressure of the air outside the body while intrapulmonary pressure is the pressure inside the alveoli of the lungs.
Air flows because of pressure differences between the atmosphere and the gases inside the lungs. When there is no movement of air, the atmospheric pressure is zero and the intrapulmonary is also zero which makes them equal.
Therefore, When there is no air movement, the relationship between the intrapulmonary and atmospheric pressure is that THEY ARE EQUAL.
